This week in adhesives news, researchers at the University of Malaya in Kuala Lumpur, Malaysia have developed a green polymer for dye-sensitized solar cells. The researchers used Chitosan, a natural polymer found in insects and crustaceans, treated with N-phthaloylation to improve solubility as the gel polymer for dye-sensitized solar cells. Dye-sensitized solar cells (DSSC) are cheaper to manufacture than silicon semiconductor based solar cells because they use less expensive components. The DSSC tested with the new biopolymer had an energy conversion rate of 7-8%.
